Abstract:
A driving apparatus is provided with: a first base portion; a first stage portion; a first elastic portion which has elasticity to displace the first stage portion in one direction (X axis); a second stage portion which is disposed on the first stage portion and on which a driven object is mounted; a second elastic portion which has elasticity to displace the second stage portion in other direction (Y axis); a first applying device for applying an excitation force for displacing the second stage portion such that the second stage portion is resonated in the other direction at a resonance frequency determined by the second stage portion and the second elastic portion; and a second applying device for applying a driving force for displacing, in a stepwise manner or in a continuous manner, the first stage portion in the one direction.
